中文摘要：

在应急管理过程中提高决策正确性的一个有效途径是去参照以往的类似事件（即＂应急案例＂）,应急案例中包含的知识可以利用语义网进行描述。首先分析一个完整的应急案例中应当包含的内容要素,主要有事件信息、指挥机构、决策指令及执行效果四项,其次对于这些要素及其相互关系采用语义图进行描述,最后通过DTD文件描述了语义图中的元素结构,通过此途径构建的基于语义网的应急案例知识表述结果,可以作为后续构建应急案例领域知识本体的基础框架。

英文摘要：

It is an effective way to refer to the past practices（＂emergency cases＂）,and the knowledge contained in the cases which can be expressed through semantic web.First there are 4 elements in a complete emergency case： the emergency itself,the command group（decision-makers）,the decision,and the performance of decision,then semantic graphs are established to describe the 4 elements and their relationship;finally DTD files are constructed to define the structure of the elements in the graphs,and the above mentioned semantic web of emergency cases can be used as the frame of domain ontology construction for emergency cases.
